Issue in void updateData(OLEDDisplay *display) with

[anduweb]

It seems that when I compile I get this:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

PS. If I use a weatherStation library newer to the first one (0.0.9) I also get a lot of the below:

Build options changed, rebuilding all

I'm using the exact hardware mentioned (Wemos D1 mini with a DHT22). Suggestions welcomed.

It compiles with no errors or warnings for me using Arduino 1.8.2 I don't know why you are getting the errors listed above.

Are you able to compile and run the Arduino File->Examples->01.Basics->blink.ino example? Have you selected the "Wemos D1 R2 & mini" board?

If you can successfully compile Blink for the Wemos D1 mini: Please make sure that you install the Software requirements from the front page:

Software Requirements/ Libraries

• Arduino IDE with ESP8266 platform installed
• ESP8266 Weather Station Library I have Version 1.2.0 installed
• ESP8266 OLED SSD1306 Library - I have Version 3.2.7 installed
• WifiManager Library - I have 0.12.0 installed
• DHT Sensor Library - I have 1.2.3 installed [ just added to the SW requirements]

Additional required library for automatic Daylight Saving Time adjust

• simpleDSTadjust Library - I have 1.2.0 installed

You also need to get an API key for the Wunderground data: https://www.wunderground.com/
